What are the main components of Cummins diesel generator set

Diesel generator set is a relatively large unit, its structure is more complex, maintenance is also very troublesome.

Main components of diesel generator set:

1. Crankshaft and main bearing crankshaft is loaded into the lower part of the cylinder block of a long shaft, on the shaft is equipped with a offset connecting rod journal, namely the crankshaft crank pin, which is used to convert the reciprocating motion of the piston connecting rod into a rotational motion. Oil supply channels are drilled inside the crankshaft to supply lubricating oil to the main bearing and the connecting rod bearing. The main bearing supporting the crankshaft in the cylinder body is a sliding bearing.

2. The cylinder block The cylinder block is the skeleton of an internal combustion engine, and all other parts of the diesel engine are mounted on the cylinder block by screws or other connections. A number of threaded holes in the cylinder block to be bolted to other parts. There are also holes or supports in the cylinder body; Drilling for supporting camshaft; Cylinder hole that fits into cylinder liner.

3. Piston, piston ring and connecting rod The piston and the piston ring in its ring groove are used to transfer the pressure of fuel and air combustion to the connecting rod connected to the crankshaft. The function of the connecting rod is to connect the piston to the crankshaft. Connecting the piston to the connecting rod is the piston pin, which is usually fully floating (the pin is floating to both the piston and the connecting rod).

4. Camshaft and timing gear in a diesel engine, the camshaft is used to control the intake and exhaust valves; In some diesel engines, it can also drive lubricating pumps or injection pumps. The CAMSHAFT is timed BY THE CRANKSHAFT BY a TIMING GEAR OR CAMSHAFT GEAR THAT IS BARED TO THE FRONT GEAR OF THE CRANKSHAFT. This not only drives the camshaft, but also keeps the diesel valve in the correct position with the crankshaft and pistons.

5. The main function of the cylinder head and valve head is to provide a cover for the cylinder. In addition, the cylinder cover from the air inlet and exhaust passage, so that air into the cylinder and exhaust gas discharge. These ports are opened and closed by actuated valves in the valve line on the cylinder head.

6. According to the load and speed of the diesel engine, the fuel system injects the exact amount of fuel into the cylinder of the diesel engine at the exact time.

7. Supercharger A supercharger is an air pump driven by exhaust gas that supplies pressurized air to the diesel engine. This increase in pressure, called supercharging, improves the efficiency of the diesel engine.

Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
